I have a system with an IntelPro Ethernet card, which purports to
support full-duplex (reformatted for legibility):
# ifconfig fxp0
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet XXX.YYY.236.105 netmask 0xfffffc00 broadcast
XXX.YYY.239.255
inet6 fe80::2d0:b7ff:fe65:d038%fxp0 prefixlen 64 scopeid 0x1
atalk 12174.21 range 12174-12174 phase 2 broadcast 0.255
ether 00:d0:b7:65:d0:38
media: autoselect (100baseTX) status: active
supported media: autoselect 100baseTX <full-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP
But trying to set full-duplex results in an error:
# ifconfig fxp0 mediaopt full-duplex
ifconfig: SIOCSIFMEDIA: Device not configured
My workaround is to have our network staff change my port on the
switch to half-duplex, but I'm hoping to learn how to do this for
future reference. Thanks.
